“The patients are fine. The surgery took nine and a half hours in total,” he said.

“The procedure is difficult because multiple large arteries are to be joined there, and veins that are small and short,” said Puntambekar. “It is technically very tough.”

The patient will have to wait a year before trying to become pregnant through in-vitro fertilization (IVF), giving her body enough time to heal and adjust to the new uterus.

According to Dr. Mats Brännström, a professor of obstetrics and gynaecology at Sweden’s University of Gothenburg, only six babies have ever been delivered from a uterus transplant — two from the same mother.

Brännström led the team that first successfully performed the procedure in 2014, when after 11 unsuccessful attempts worldwide by their team and others, a healthy baby was born in Sweden.

All five babies delivered since have been the result of surgeries performed by the Swedish team.

It remains to be seen whether India’s first transplant will result in a birth.

“We are responsible for the patient and fulfilling their dreams of becoming a mother, which was impossible for them until now,” Puntambekar said, adding that he was aware of the “responsibility on his shoulders,” but was feeling “relaxed and confident.”

Successful uterus transplants are rare because of the complexity of the procedure involved: this was the first attempt at the pioneering surgery in India and only the 30th attempt in the world.

Attempts have also taken place in the United States, Brazil, Sweden, China, Germany, Serbia, Czech Republic, Saudi Arabia and Turkey, said Brännström.
